[tex]\sqrt{2}[/tex]Answer:
Step-by-step explanation:
now the equations looks like
5-4*Cos(x) = y
when 45° gets plugged into Cos(x) we get [tex]\sqrt{2}[/tex]/2 again
5- 4 * ([tex]\sqrt{2}[/tex]/2) = y
5-2[tex]\sqrt{2}[/tex]=y
leave it in that form . it's exact that way

(3x + 7)(3x – 9)
Answers
Answer:
9x² - 6x - 63
Step-by-step explanation:
Use the FOIL method. FOIL stands for First, Outside, Inside, Last.
Multiply following the FOIL:
3x * 3x = 9x²
3x * -9 = -27x
7 * 3x = 21x
7 * -9 = -63
9x² - 27x + 21x - 63
Combine like terms.
9x² (-27x + 21x) - 63
9x² - 6x - 63
9x² - 6x - 63 is your answer.
~
9x^2 - 27x+21x−63
9x^2 + (27x+21x) - 63
9x^2 - 6x - 63

Given function:
g(x) = x² - 6x + ca)
c = 2Th x-intercept found when g(x) = 0
x² - 6x + 2 = 0Solve the equation to find the values of x:
x² - 6x + 2 = 0x² - 6x + 9 = 7(x - 3)² = 7x - 3 = ±√7x = 3 ± √7The x-intercepts are (3 + √7, 0) and (3 - √7, 0)
b)
c = 10Solve as above:
x² - 6x + 10 = 0x² - 6x + 9 + 1 = 0(x - 3)² = -1The left side is a square of a number which is always positive, the right side is negative.
It means there is no solution, so no-x-intercepts.
The graph of the function lies above the x-axis.

Mr. Choe solved the inequality and his work is shown below. 3x+5≤−1 −5 −5 3x≤−6 ÷3 ÷3 x≥−2 Identify and explain Mr. Choe's error.
Answers
Answer:
x ≤ - 2
Step-by-step explanation:
Given the inequality :
3x+5≤−1
Subtract 5 from both sides
3x + 5 - 5 ≤ - 1 - 5
3x ≤ - 6
Divide both sides by 3
3x/3 ≤ - 6/3
x ≤ - 2
Mr.Choe's error was that he changed the inequality sign. The inequality sign in this case does not need to be changed.

A storage shed is a rectangular prism and has dimensions of 6 meters by 5 meters by 12 meters. If Jean were to double these dimensions, she believes she would only double the volume. Is she correct? Explain why or why not. Include a drawing in your explanation.
Answers
Answer:
Hence doubling the dimension gives a volume greater than doubling the original volume.
Step-by-step explanation:
Given The dimension :
Original dimension : 6 meters by 5 meters by 12 meters
Volume of original dimension :
6 * 5 * 12 = 360 m³
If dimension is doubled :
2 * 6 = 12
2 * 5 = 10
2 * 12 = 24
Volume = (12 * 10 * 24) = 2880 m³
2 * original volume = 2 * 360 = 720 m³
Hence doubling the dimension gives a volume greater than doubling the original volume.

A Fisherman spent his weekend working on his farmland
He had 1/6 of a bag of soil
He spreads it evenly among his 2 garden beds
Therefore the soil in each garden bed can be calculated as follows
= 1/6 ÷ 2
= 1/6 × 1/2
= 1/12 per bag
